How does addition of AgCl affect concentration of iodide in KI solution?
In a mixture of $\ce{AgCl(s)}$ and initial $\pu{0.10 M}$ $\ce{KI}$, what is the $[\ce{I-}]$ after the reaction proceeds?
Disclaimer: This is not a graded assignment, but rather a problem I'm trying to ...

Why is the Ag+ concentration in a beaker fixed in the reaction between excess AgCl (s) and KI (aq) from the start? [duplicate]
This arises as a sub-question for the following question: Calculate the concentration of I- in a solution obtained by mixing 0.10 M KI with an excess of AgCl(s).
I tried to look at How does addition ...

Is there a quick way to approximate a logarithm in Nernst equation?
The problem is as follows:
In a galvanic cell the cathode is an $Ag^{+}(1.00\,M)/Ag_{(s)}$
half-cell. The anode is a standard hydrogen electrode immersed in a
buffer solution containing $0.10\,...

How to calculate the equivalent mass of Na2S2O3? [closed]
Let us consider the following reaction
$$\ce{I2 + 2 Na2S2O3 -> 2 NaI + Na2S4O6}$$
Now, in order to calculate the equivalent mass of $\ce{Na2S2O3}$, first I need to calculate it's $n$-factor which ...

Calculating PH of solution after adding strong acid (equilibrium)
Consider the classic example when talking about acids and bases:
Say you have 1M of $\ce{HCL}$ and you throw it into water, calculate the resulting pH (= concentration of $\ce{H3O+}$).
The way this ...

Problem
What would charge would you expect on alanine when placed in a solution with a pH of 1.00?
Answer
Question
Let's say I am given a certain pH of 2.00 rather than 1.00 for the "acidic ...
